The phrase works as a tiny piece of storytelling that needs no context, which is why it has circulated as a reusable reaction clip on soundboards and in short-form edits. Creators treat the words as a setup and the boom as the payoff, so it fits memes about sudden disasters, unexpected endings and exaggerated cause and effect. Its popularity comes from timing rather than a famous source line, and it remains useful because viewers understand the joke from the sound alone in under two seconds, even on mute-off autoplay edits.
关于此声音
A short spoken line saying 'and then boom' followed by a sudden explosive hit, used in videos for surprise reveals, crashes and fast punchline moments.
This clip pairs a casual spoken setup with a sudden impact. A voice says and then boom in a flat, storytelling tone, and the last word lands right as a deep boom sound hits. The contrast makes it feel like something just exploded, collapsed or went wrong off screen. It is brief and punchy, so the joke registers instantly without needing a visual explanation. Viewers hear the expectation in the lead-in and the payoff in the boom, which makes the moment work as a quick reaction or a comic transition between scenes.
